Google has donated £550,000 to a project that aims to turn Britain’s Bletchley Park into a world-class heritage and education centre. The money goes a long way towards helping the Bletchley Park Trust match a previous £4.6m grant from the Heritage Lottery Fund.

The Bletchley Park project aims to restore the iconic codebreaking huts 1, 3 and 6 and to build a high-tech visitor centre that can be used to educate visitors about the site’s crucial role during World War 2. It was at Bletchley Park that Britain’s top cryptographers worked during the war, helping decode German messages.
